    1. Correlation between pigmented arc and epithelial thickness (COPE) study in orthokeratology-treated patients using OCT measurements

      Correlation between pigmented arc and epithelial thickness (COPE) study in orthokeratology-treated patients using OCT measurements

      Purpose To determine the intensity of corneal pigmented arc in orthokeratology (ortho-k)-treated children, and its correlation with key epithelial thickness measurements obtained by anterior segment optical coherence tomography (AS-OCT). Methods This study is a retrospective case series. Medical records of children who received ortho-k treatment for myopia control in our hospital were reviewed. Intensity of ortho-k-associated pigmented arc and its correlation with key epithelial thickness parameters in the central 7-mm-diameter zone obtained by AS-OCT was examined. The subjects were further divided into apparent and unapparent pigmented arc groups for severity comparison. Results The mean age of children was 11 ...

    2. NOVEL OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY BIOMARKER IN BRANCH RETINAL VEIN OCCLUSION MACULAR EDEMA

      NOVEL OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY BIOMARKER IN BRANCH RETINAL VEIN OCCLUSION MACULAR EDEMA

      Purpose: To evaluate the association between deep–superficial flow ratio (DSFR) and the treatment response of macular edema in branch retinal vein occlusion . Methods: Thirty eyes from 30 patients with branch retinal vein occlusion who had received optical coherence tomography angiography examination were included. Seventeen normal fellow eyes acted as the control group. Patients were classified into the “good response group” and the “refractory group” by absence or presence of macular edema after 6 months of treatment. The DSFRs were calculated by dividing deep capillary plexus vessel density by superficial capillary plexus vessel density on optical coherence tomography angiography . Results ...

    3. Correlation between spectral domain optical coherence tomography findings and visual outcomes in central retinal vein occlusion

      Correlation between spectral domain optical coherence tomography findings and visual outcomes in central retinal vein occlusion
      Purpose: To investigate the relationship between spectral domain optical coherence tomography (SD-OCT) findings and visual outcomes following resolution of macular edema in central retinal vein occlusion (CRVO). Methods: Patients with recent onset CRVO who had undergone SD-OCT and fluorescein angiography (FA) exams on the day of initial presentation were included. All patients had resolution of macular edema in SD-OCT images at the end of follow-up, and they were separated into two groups according to final visual acuity: group 1 (≤ 20/200) and group 2 (> 20/200). SD-OCT scans and FA studies were analyzed in a masked fashion. Macular perfusion status ...

    4. Correlation between Spectral Domain Optical Coherence Tomography Findings and Fluorescein Angiography Patterns in Diabetic Macular Edema

      Objective: To study the relationship between spectral domain optical coherence tomography (SD-OCT) findings and fluorescein angiography (FA) patterns in patients with diabetic macular edema (DME). Design: Retrospective, observational, cross-sectional study. Participants: We included 59 eyes from 59 patients with DME that had SD-OCT/scanning laser ophthalmoscope (SLO) and FA performed on the same day. Eyes with macular edema owing to other ocular diseases were excluded. Methods: The relationship between SD-OCT and FA findings was evaluated by superimposing and aligning the SLO images onto the FA photos. The SLO image of the OPKO/OTI Spectral OCT/SLO (OPKO-OTI, Miami, FL) corresponds ...
